Northbrook resident Lily Krefetz had a once-in-a-lifetime invitation to go to The Academy Awards on March 2. Her date was her son, Glenbrook North alum Nathan Ross, an executive producer of the award-winning “Dallas Buyers Club.” “I took my mom to the premiere of the film at the Toronto Film Festival last September, and it’s who I wanted to share [the Oscars] with,” Ross said. “I invited her on Valentine’s Day … predictably, she got very emotional, and it was a nice little treat.”
